BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Lavandula plant, botanically known as Lavandula stoechas pedunculata, commonly referred to as Spanish Lavender and hereinafter referred to by the name ‘FW Radiance’.

The new Lavandula plant is a product of a planned breeding program conducted by the Inventor in Wonga Park, Victoria, Australia. The objective of the breeding program was to develop new compact and freely-flowering Lavandula plants with good garden performance and attractive plant form and flower coloration.

The new Lavandula plant originated from a cross-pollination in October, 2009 of Lavandula stoechas pedunculata ‘Papillon’, not patented, as the female or seed, parent with Lavandula stoechas pedunculata ‘Strawberry Ruffles’, disclosed in U.S. Plant Pat. No. 22,490, as the male, or pollen, parent. The new Lavandula plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Wonga Park, Victoria, Australia in October, 2014.

Asexual reproduction of the new Lavandula plant by softwood terminal cuttings in a controlled greenhouse environment in Wonga Park, Victoria, Australia since December, 2014 has shown that the unique features of this new Lavandula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lavandula have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the new Lavandula plant. These characteristics in combination distinguish ‘FW Radiance’ as a new and distinct Lavandula plant:

1. Compact and broadly upright plant habit.

2. Freely branching growth habit, dense and bushy appearance.

3. Freely flowering habit.

4. Purple-colored flowers with medium to large red purple-colored sterile flower bracts arranged on short terminal spikes.

5. Good garden performance.

Plants of the new Lavandula differ primarily from plants of the female parent, ‘Papillon’, in the following characteristics:

1. Plants of the new Lavandula are more upright than and not as spreading as plants of ‘Papillon’.

2. Plants of the new Lavandula have broader sterile flower bracts than plants of ‘Papillon’.

3. Plants of the new Lavandula and ‘Papillon’ differ in sterile flower bract color as flowers of plants of the new Lavandula have red purple-colored sterile flower bracts whereas flowers of plants of ‘Papillon’ have mauve-colored sterile flower bracts.

Plants of the new Lavandula differ primarily from plants of the male parent, ‘Strawberry Ruffles’, in the following characteristics:

1. Plants of the new Lavandula have shorter inflorescences than plants of ‘Strawberry Ruffles’.

2. Plants of the new Lavandula have narrower sterile flower bracts than plants of ‘Strawberry Ruffles’.

3. Plants of the new Lavandula and ‘Strawberry Ruffles’ differ in sterile flower bract color as flowers of plants of the new Lavandula have brighter red purple-colored sterile flower bracts than flowers of plants of ‘Strawberry Ruffles’.

4. Plants of the new Lavandula have longer peduncles than plants of ‘Strawberry Ruffles’.

Plants of the new Lavandula can be compared to plants of Lavandula stoechas pedunculata ‘FW Spellbound’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Lavandula and ‘FW Spellbound’ differ primarily in flower color as flowers of plants of the new Lavandula are purple in color with red purple-colored sterile flower bracts whereas flowers of plants of ‘FW Spellbound’ are dark violet in color with purple violet-colored sterile flower bracts.

Plants of the new Lavandula can be compared to plants of Lavandula stoechas pedunculata ‘FW Whimsical’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Lavandula and ‘FW Whimsical’ differ primarily in flower color as flowers of plants of the new Lavandula are purple in color with red purple-colored sterile flower bracts whereas flowers of plants of ‘FW Whimsical’ are light purple in color with light red purple-colored sterile flower bracts.

Plants of the new Lavandula can be compared to plants of the Lavandula stoechas ‘IBPR910-2’, disclosed in U.S. Plant Pat. No. 25,525. In side-by-side comparisons, plants ofthe new Lavandula differ primarily from plants of ‘IBPR910-2’ in the following characteristics:

1. Plants of the new Lavandula have shorter inflorescences than plants of ‘IBPR910-2’.

2. Plants of the new Lavandula have narrower sterile flower bracts than plants of ‘IBPR910-2’.

3. Sterile flower bracts of plants of the new Lavandula are more outwardly spreading than and not as upright as sterile flower bracts of plants of ‘IBPR910-2’.

4. Margins of sterile flower bracts of plants of the new Lavandula are not as undulate as margins of sterile flower bracts of plants of ‘IBPR910-2’.

Plants of the new Lavandula can also be compared to plants of the Lavandula stoechas ‘Bentley’, disclosed in U.S. Plant Pat. No. 22,709. In side-by-side comparisons, plants of the new Lavandula differ primarily from plants of ‘Bentley’ in the following characteristics:

1. Plants of the new Lavandula have longer sterile flower bracts than plants of ‘Bentley’.

2. Plants of the new Lavandula and ‘Bentley’ differ in sterile flower bract color as flowers of plants of the new Lavandula have darker red purple-colored sterile flower bracts than flowers of plants of ‘Bentley’.

3. Plants of the new Lavandula have longer peduncles than plants of ‘Bentley’.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and following detailed description were grown in 20-cm containers during the spring in an outdoor nursery in Wonga Park, Victoria, Australia and under cultural practices typical of commercial Lavandula production. Plants were pinched two times and were one year old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 10° C. to 40° C. and night temperatures ranged from −1° C. to 20° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
